An object of the'invention is to providas'uch a homer whichwill provide a handy' grip in means for materials such as'steel' wool, fabric waste; rags, cloth,"etc., so that they may'beu'sed while avoiding direct "contact with the" hands,

a holder so designed tl'iat the hands are kept =-from contact with the-object being scoured or cleaned.

Another object of the invention is to provide a holder having positive internal" "gripping means forthe scouring or cleanin'g inaterial, s'aid g rip Y ping means being simple of construction and easy to engage with and disengage from the-material 1 'to be used. A further advan't'ag'eof said gripping to catch in the usrshari'ds or' clothes, or tending to interfere with'the scouring or cleai'iing operation. n

" A- further object-of the 'invention is-to: provide a holder capable of gripping portions of bulk steel wool or the like, it not being necessary to have the scouring or cleaning material molded or preformed in any particular shape in order to be adaptable to the holder.

A further object of the invention is to provide a simple and durable holder which is cheap to construct, and which has a minimum of operational parts which could break or deteriorate.

Other objects of the invention will be understood from the description of the drawing which follows. In said drawing:

Fig. 1 is a side view, with broken away portions in section, showing one modification of the invention;

Fig. 2 is a sectional view taken on the lines 2-2 of Fig. l, but with the abrasive or cleaning material shown in Fig. 1 omitted;

Fig. 3 is a side view, with broken away portions in section, showing the invention with modified material gripping means;

Fig. 4 is a sectional view showing another modification of the invention;

Fig. 5 is a sectional view showing a further modification of the invention; and

Fig. 6 is a perspective detail of the disc which forms part of the material gripping means of the modifications of Figs. 4 and 5.

In these figures the invention has been illustrated as having a body composed of plastic material, which material will be found to be well suited therefor; it is obvious however, that the 2 some may-be constructed'of woodfinetaljofany other material adaptable to the purposes "'o'fthe f iliiviition. v v

""'In"Fig.. 1',"the body"lo issnownes refined of 5"" "q interlocking sections IT'andIfwhibhforfif a :"1 nfi'ded"body"'surfaice and a're joined 'asby a friction ors'napjoint I3. -'snapiioint' I3 is a con- Venient means o'f"closing"the body I; however, thisparticular means does not 'form an"'essentia1 lOi part of 'theirivention, and other closing means of 'fficie'nt' strength maybe substituted; such as a fscrew' threaded 'joint. K

""Iiiteriorly of -the" u per half 1 I""ofbodyI is forn'ied p1ojecting"'seat"I G over which the end 1515f s'pringl ii'is "coiled; "thus positioning said spring operativeposition'* The lower end of spring I is formed in 'a'flat 'loop'"I 6;whichfloop is slightly "larger than the; lower opening of body I U,-'-as'may "be"best""seen in Fig 2.

tapered -tofo'rm a"circularmpeningfand' project- "i'n'g inwardly and upwardly of "said"'openin are "'frmedintegrally 'with"b6dy"IIl thesubstantially g'id' materialgripping'teeth I'I. These'te'ethare adapted to 'cobperat'with the lower loop 16 of sp'ringl5" to "provideeiampmg means for the scouring or cleaning material to be'placed in the "holder.

In Fig. 1, such material, indicated at I8, is shown in operable position in the holder. To insert such material in the holder all that is necessary is to insert a portion thereof through the lower opening of holder II], thus raising spring I5. The portions of the material entering the opening will thus be caught and held by the clamping and biting action of loop I6 and teeth II. To remove the cleaning material I8, spring I5 may be raised as with the finger, and material I8 may then be disengaged from teeth II; or, the holder II] may be opened at joint I3 and spring I5 may be removed.

In the modification shown in Fig. 3, the holder I0 and the spring I5 are the same as previously described; however, in this modification there is added a seating disc I9 inwhich is seated the lower end of spring I5. Seating disc I9 provides a larger and flatter contact surface than does the end I6 of spring I5, and may be employed when it is desired to increase the gripping action against the teeth II.

In the modification of Fig. 4, the holder I0 is again as previously described. In this modification a U-shaped spring 20 is employed in place of the coil spring I5 just described. Gripping contact with the material I8 is provided .by disc 2| which is formed with a punched out loop 22 adapted to fit over and be carried on spring 20. The gripping action of this modification is provided by the thrust of spring 20 which presses the material [8 between disc 2| and teeth H. A perspective of disc 2| is shown in Fig. 6.

In the modification of Fig. 5, disc 2|, as just described, cooperates in the same manner with teeth H, but is activated by ans-shaped spring 23. A seat 24 is provided on the inner wall of holder III to hold in place the upper end of spring 23.

In the claims which follow the word material is used as a short definition of all cleaning, scouring, or polishing materials capable of being placed in and used with the holder constituting the invention, and includes the materials specifically suggested for use therewith in the above description.

Having thus described the invention, what is claimed is:

1. A material holder suitable for manual polishing, scouring, cleaning, or the like, comprisin a hollow body having a relatively large convex upper rounded portion of dimensions providing a hand grip, said upper portion tapering into a lower relatively small material-gripping portion terminating in an open mouth; a plurality of substantially rigid projecting teeth formed integrally of the body material around the inner periphery of said open mouth, said teeth extending inwardly and upwardly into said hollow body, spring clamping means compressed in the body exerting an expansion force in the direction of said mouth from a bearing surface on said upper hand grip portion of the body, said spring clamping means extending from said bearing surface and in inoperative position being in compressive engagement against said teeth, said clamping means being actuable by the entrance of a small amount of material into said mouth to clamp said amount of material against said upwardly projecting teeth, thereby holding said material with the major portion thereof in position for use externally of said hollow body.

2. The invention according to claim 1, said internal spring clamping means comprising a 4 coil spring extending longitudinally of the body from a, seat opposite the mouth of the holder and terminating adjacent said material engaging teeth.

3. The invention according to claim 1, said internal spring clamping means comprising a coil spring disposed longitudinally of the body on a seat opposite the mouth of the holder and carrying a disc adjacent said teeth, said disc bein actuated by said sprin to clamp that portion of the. material inserted into the mouth from outside the holder.

4. The invention according to claim 1, said;

internal spring clamping means comprising an S-shaped spring disposed in the holder and f:

carrying a flat disc adjacent said teeth, said disc being actuated by said spring to clamp that portion of the material inserted into the mouth from outside the holder against said teeth.

5. The invention according to claim 1, said internal spring clampin means comprising a U-shaped spring disposed in the holder and i carrying a flat disc adjacent said teeth, said disc being actuated by said spring to clamp that portion of the material inserted into the mouth from outside the holder against said teeth.
